Description

シートSheet
　本発明は、表皮に開口が形成されたシートに関する。 The present invention relates to a sheet having an opening formed in the epidermis.
　従来、車両用シートなどにおいて、種々の目的のために表皮に開口が形成されたシートが用いられている。 Conventionally, in vehicle seats and the like, seats having openings formed in the skin have been used for various purposes.
　例えば、特許文献１に記載されているシートでは、シートバックに隣接するサイドシートの略垂直方向に延びる壁部分において、車内換気用の矩形形状の開口が表皮に形成されている。このシートでは、表皮の開口周囲の部分のしわの発生を抑制するために、表皮の開口の周辺には、表皮の外側からベゼルが取り付けられ、表皮の内側には、樹脂プレートが取り付けられている。ベゼルおよび樹脂プレートは、いずれも表皮の平面部分に形成された開口の周辺部分に当接するように、平面的な矩形の枠体形状をしている。 For example, in the seat described in Patent Document 1, a rectangular opening for ventilation inside the vehicle is formed in the epidermis in a wall portion extending in a substantially vertical direction of a side seat adjacent to the seat back. In this sheet, in order to suppress the occurrence of wrinkles around the opening of the epidermis, a bezel is attached from the outside of the epidermis around the opening of the epidermis, and a resin plate is attached to the inside of the epidermis. .. Both the bezel and the resin plate have a flat rectangular frame shape so as to abut the peripheral portion of the opening formed in the flat portion of the epidermis.
　この構成では、樹脂プレートが表皮を内側から押さえているので、ベゼルが表皮を外側から押さえても表皮が内側に沈み込むことが抑制され、表皮におけるしわの発生が抑制される。 In this configuration, since the resin plate presses the epidermis from the inside, even if the bezel presses the epidermis from the outside, the epidermis is suppressed from sinking inward, and the occurrence of wrinkles on the epidermis is suppressed.
　近年の表皮に開口が形成されたシートには、表皮の曲面部分に開口が形成された構成を有するシートが提案されている。 As a sheet having an opening formed in the epidermis in recent years, a sheet having a structure in which an opening is formed in a curved surface portion of the epidermis has been proposed.
　例えば、ＩＳＯＦＩＸと呼ばれる国際標準規格の固定方式のチャイルドシートを取付可能な構造を有するシートでは、当該ＩＳＯＦＩＸ方式のチャイルドシートの後部に設けられたコネクタと連結するために、シートクッションの後端の円柱状に盛り上がった曲線部分においてコネクタ挿入用の開口を有している。このようなシートでは、表皮の曲面部分に湾曲した開口が形成される。この湾曲した開口の周辺部分を保持するためには、表皮の曲面部分を内側から樹脂プレートを当接させた状態で、湾曲したベゼルによって表皮を外側から押さえる必要がある。 For example, in a seat having a structure in which an international standard fixed child seat called ISOFIX can be attached, in order to connect with a connector provided at the rear of the ISOFIX child seat, a columnar shape at the rear end of the seat cushion is formed. It has an opening for inserting a connector in the raised curved portion. In such a sheet, a curved opening is formed in the curved portion of the epidermis. In order to hold the peripheral portion of the curved opening, it is necessary to press the epidermis from the outside with the curved bezel while the curved portion of the epidermis is in contact with the resin plate from the inside.
　しかし、表皮の曲面部分の外側からベゼルで押さえた場合、樹脂プレート全体がベゼルに沿うように凹んで表皮の曲面部分から離れる部分が生じるため、当該曲面部分の曲面に樹脂プレートを沿わせることは困難である。その結果、表皮の曲面部分の開口周辺におけるしわの発生を抑制することは困難である。 However, when the resin plate is pressed from the outside of the curved surface portion of the epidermis with the bezel, the entire resin plate is dented along the bezel and a portion is separated from the curved surface portion of the epidermis. Have difficulty. As a result, it is difficult to suppress the occurrence of wrinkles around the opening of the curved surface portion of the epidermis.
特開２０１７―１９００９４号公報Japanese Unexamined Patent Publication No. 2017-190094
　本発明の目的は、表皮の曲面部分の開口周辺におけるしわの発生を抑制することが可能なシートを提供することである。 An object of the present invention is to provide a sheet capable of suppressing the occurrence of wrinkles around the opening of the curved surface portion of the epidermis.
　上記の課題を解決するために、本発明のシートは、少なくとも一部に曲面部分を有し、当該曲面部分において当該曲面部分に沿うように所定の曲線方向に湾曲した開口が形成された表皮と、前記曲面部分における前記開口の周辺部分を補強する弾性変形可能な板状の補強部材であって、前記曲面部分の内側の面に沿うように湾曲した状態で配置された補強部材と、前記曲面部分の外側の面から前記開口の周辺部分を押圧した状態で覆う押圧部材とを備えており、前記補強部材は、前記押圧部材に重なって前記押圧部材と協働して前記表皮を挟む本体部分と、前記本体部分の前記曲線方向に直交する幅方向における少なくとも一方の側縁につながり前記押圧部材に重ならない範囲に延設された延設部分とを有しており、前記延設部分には、スリットが形成され、前記スリットは、前記延設部分における幅方向外側の部分が前記本体部分から独立して弾性変形できるように、前記曲線方向に延びている、ことを特徴とする。 In order to solve the above-mentioned problems, the sheet of the present invention has a curved surface portion at least in a part thereof, and has a skin having an opening curved in a predetermined curved direction along the curved surface portion. An elastically deformable plate-shaped reinforcing member that reinforces a peripheral portion of the opening in the curved surface portion, and a reinforcing member arranged in a curved state along the inner surface of the curved surface portion, and the curved surface portion. A pressing member that covers the peripheral portion of the opening in a pressed state from the outer surface of the portion is provided, and the reinforcing member overlaps the pressing member and cooperates with the pressing member to sandwich the skin. And an extension portion connected to at least one side edge of the main body portion in the width direction orthogonal to the curve direction and extended to a range not overlapping with the pressing member, and the extension portion has an extension portion. The slit is formed, and the slit extends in the curved direction so that the outer portion in the width direction of the extended portion can be elastically deformed independently of the main body portion.

The seat 1 shown in FIG. 1 is a seat used for a passenger seat or a rear seat of an automobile, and has a structure in which an ISOFIX fixed child seat can be detachably attached. That is, in a seat structure having a seat cushion 2 as a seat and a seat back 3 as a backrest, the seat 1 may cover the pad 5 (see FIG. 9) and the surface of the pad 5 on the seat cushion 2 side. It includes a skin 6 having a possible shape, and a connector mounting portion 4 that can be connected to a child seat connector (not shown). In the present embodiment, the connector mounting portion 4 is provided at a raised portion (see the curved surface portion 6b of the skin 6) of the rear end (end portion on the seat back 3 side) of the seat cushion 2.
　シートクッション２の表皮６についてさらに詳しく言えば、表皮６は、図７に示されるように、少なくとも一部、具体的には表皮６の後端付近において上方に盛り上がった半円柱状の曲面部分６ｂを有する。当該曲面部分６ｂにおいて当該曲面部分６ｂに沿うように所定の曲線方向Ｃに湾曲した表皮開口部６ａが形成されている。具体的には、表皮開口部６ａは、前方から上方に向かう範囲において外向きに膨らむように湾曲している。表皮開口部６ａは、シート１の両側の側縁（図１および図９に示されるシート１の幅方向Ｘにおける表皮６の側縁６ｄ）に近い位置に形成されている。 More specifically, as shown in FIG. 7, the skin 6 of the seat cushion 2 is a semi-cylindrical curved surface portion 6b that rises upward at least in part, specifically near the rear end of the skin 6. Has. In the curved surface portion 6b, an epidermis opening 6a curved in a predetermined curved direction C is formed along the curved surface portion 6b. Specifically, the epidermis opening 6a is curved so as to bulge outward in a range from the front to the top. The skin opening 6a is formed at a position close to the side edges of both sides of the sheet 1 (side edges 6d of the skin 6 in the width direction X of the sheet 1 shown in FIGS. 1 and 9).
　コネクタ取付部４は、図９に示されるように、パッド５および表皮６にそれぞれ形成されて互いに連通するように配置された矩形形状のパッド開口部５ａおよび表皮開口部６ａと、当該パッド開口部５ａの内部にチャイルドシートのコネクタが係合可能な被係合部としてのコの字状の金属バー１０（図２参照）とを備えた構造を有している。パッド開口部５ａおよび表皮開口部６ａは、コネクタが挿入可能な大きさを有する。金属バー１０は、その中央部分がパッド開口部５ａを横断する方向に延びるように、パッド開口部５ａの内部に配置される。金属バー１０は、シート１のパッド５を支持する金属製フレーム（図示略）に連結されている。 As shown in FIG. 9, the connector mounting portion 4 includes a rectangular pad opening 5a and a skin opening 6a formed on the pad 5 and the skin 6 and arranged so as to communicate with each other, and the pad opening. 5a has a structure provided with a U-shaped metal bar 10 (see FIG. 2) as an engaged portion to which the connector of the child seat can be engaged. The pad opening 5a and the skin opening 6a have a size into which a connector can be inserted. The metal bar 10 is arranged inside the pad opening 5a so that its central portion extends in a direction traversing the pad opening 5a. The metal bar 10 is connected to a metal frame (not shown) that supports the pad 5 of the sheet 1.
　コネクタ取付部４は、さらに、図２～６に示されるように、表皮６の内側におけるパッド開口部５ａの内部に配置されてコネクタを受けるベゼル７と、当該ベゼル７の外側を覆うカバー８と、矩形形状の表皮開口部６ａの周縁部を補強する補強部材としての補強プレート９とを備えている。補強プレート９の具体的な構成については、後段で詳細に説明する。 Further, as shown in FIGS. 2 to 6, the connector mounting portion 4 includes a bezel 7 arranged inside the pad opening 5a inside the skin 6 to receive the connector, and a cover 8 covering the outside of the bezel 7. A reinforcing plate 9 is provided as a reinforcing member for reinforcing the peripheral edge of the rectangular skin opening 6a. The specific configuration of the reinforcing plate 9 will be described in detail later.
　ベゼル７およびカバー８は、ねじなどの締結部材（図示せず）で互いに連結された状態で、パッド開口部５ａ（図９参照）の内部に配置されている。 The bezel 7 and the cover 8 are arranged inside the pad opening 5a (see FIG. 9) in a state of being connected to each other by a fastening member (not shown) such as a screw.
　ベゼル７は、図２～５に示されるように、表皮６の表側における表皮開口部６ａの周縁部に当接する表側当接部７ａと、コネクタを受け入れることが可能な斜め前方に開放された形状を有する受け部７ｂとを有している。具体的には、受け部７ｂは、受け部７ｂの幅方向（後述の幅方向Ｗと同じ方向）に離間した一対の側壁と、底壁と、後壁とを有し、前方から上方にかけて開放された箱型形状を有する。これらの表側当接部７ａおよび受け部７ｂが樹脂によって一体成形されることにより、本実施形態のベゼル７が構成されている。ベゼル７は、表側当接部７ａを有していることによって、表皮６を外側から押圧する押圧部材として機能することが可能である。 As shown in FIGS. 2 to 5, the bezel 7 has a front side contact portion 7a that abuts on the peripheral edge portion of the skin opening 6a on the front side of the skin 6, and a shape that is open diagonally forward to accept the connector. It has a receiving portion 7b having the above. Specifically, the receiving portion 7b has a pair of side walls, a bottom wall, and a rear wall separated in the width direction of the receiving portion 7b (the same direction as the width direction W described later), and is opened from the front to the upper side. It has a box-shaped shape. The bezel 7 of the present embodiment is formed by integrally molding the front contact portion 7a and the receiving portion 7b with a resin. By having the front side contact portion 7a, the bezel 7 can function as a pressing member that presses the skin 6 from the outside.
　受け部７ｂは、図２～３に示されるように、前方から上方にかけての範囲に開放してコネクタを受け入れることが可能なコネクタ挿入空間７ｅを有する。また、受け部７ｂには、金属バー１０（図２参照）の中央部分がコネクタ挿入空間７ｅの内部に突出できるように、スリット７ｃが形成されている。さらに、受け部７ｂの外側には、金属バー１０（図２参照）の一対の腕部分を保持する保持部７ｄが設けられている。 As shown in FIGS. 2 to 3, the receiving portion 7b has a connector insertion space 7e that can be opened in a range from the front to the upper side to accept the connector. Further, a slit 7c is formed in the receiving portion 7b so that the central portion of the metal bar 10 (see FIG. 2) can protrude into the connector insertion space 7e. Further, on the outside of the receiving portion 7b, a holding portion 7d for holding a pair of arm portions of the metal bar 10 (see FIG. 2) is provided.
　表側当接部７ａは、表皮６の表側における表皮開口部６ａの周縁部に当接することが可能な形状を有する。本実施形態では、表側当接部７ａは、表皮開口部６ａの湾曲した矩形形状の周縁部と相似形となる湾曲した矩形形状を有し、表皮開口部６ａの周縁部の表面の全周に当接することが可能である。 The front side contact portion 7a has a shape capable of contacting the peripheral edge portion of the skin opening 6a on the front side of the skin 6. In the present embodiment, the front side contact portion 7a has a curved rectangular shape similar to the curved rectangular peripheral portion of the epidermis opening 6a, and covers the entire surface of the peripheral surface of the epidermis opening 6a. It is possible to abut.
　カバー８は、図２～３に示されるように、ベゼル７の受け部７ｂを下側から覆ってベゼル７の外部に係合可能な構成を有する。また、カバー８は、表皮６の裏側において補強プレート９に当接する裏側当接部８ａを有している。 As shown in FIGS. 2 to 3, the cover 8 has a configuration in which the receiving portion 7b of the bezel 7 is covered from below and can be engaged with the outside of the bezel 7. Further, the cover 8 has a back side contact portion 8a that contacts the reinforcing plate 9 on the back side of the skin 6.
　図８に示されるように、ベゼル７は、カバー８とともに表皮６および補強プレート９を挟みながら、カバー８に取り付けられる。すなわち、表皮６の曲面部分６ｂの内側の面に補強プレート９が取り付けられた状態で、ベゼル７の受け部７ｂを表皮開口部６ａに挿入する。ベゼル７の受け部７ｂは、表皮６および補強プレート９を貫通してカバー８に係合する。この状態では、図２～３に示されるように、ベゼル７の表側当接部７ａは、表皮６の外側の面から表皮開口部６ａの周辺部分を押圧した状態で覆う。これによって、ベゼル７の表側当接部７ａとカバー８の裏側当接部８ａとによって、表皮６および補強プレート９を挟んで保持することが可能である。 As shown in FIG. 8, the bezel 7 is attached to the cover 8 while sandwiching the skin 6 and the reinforcing plate 9 together with the cover 8. That is, with the reinforcing plate 9 attached to the inner surface of the curved surface portion 6b of the skin 6, the receiving portion 7b of the bezel 7 is inserted into the skin opening 6a. The receiving portion 7b of the bezel 7 penetrates the skin 6 and the reinforcing plate 9 and engages with the cover 8. In this state, as shown in FIGS. 2 to 3, the front contact portion 7a of the bezel 7 covers the peripheral portion of the epidermis opening 6a from the outer surface of the epidermis 6 in a pressed state. As a result, the skin 6 and the reinforcing plate 9 can be sandwiched and held by the front side contact portion 7a of the bezel 7 and the back side contact portion 8a of the cover 8.
　（補強プレートの説明）
　補強プレート９は、図２～７に示されるように、表皮６の曲面部分６ｂにおける表皮開口部６ａの周辺部分を補強する弾性変形可能な板状の部材である。 (Explanation of reinforcing plate)
As shown in FIGS. 2 to 7, the reinforcing plate 9 is an elastically deformable plate-shaped member that reinforces the peripheral portion of the skin opening 6a in the curved surface portion 6b of the skin 6.
　補強プレート９は、弾性変形可能であり、かつ、表皮６の曲面部分６ｂの形状を保持可能な曲げ剛性を有する材料として、例えば、熱可塑性樹脂板（例えば、ポリプロピレン）などで構成されている。 The reinforcing plate 9 is made of, for example, a thermoplastic resin plate (for example, polypropylene) as a material having elastic deformation and bending rigidity capable of holding the shape of the curved surface portion 6b of the skin 6.
　補強プレート９は、表皮６の曲面部分６ｂの内側の面に沿うように前記曲線方向Ｃ（図７参照）に湾曲した状態で配置されている。 The reinforcing plate 9 is arranged in a curved state in the curved direction C (see FIG. 7) so as to be along the inner surface of the curved surface portion 6b of the skin 6.
　補強プレート９は、本体部分９ａと、当該本体部分９ａの前記曲線方向Ｃ（図７参照）に直交する幅方向Ｗにおける両側に設けられた延設部分９ｂ、９ｃとを有している。 The reinforcing plate 9 has a main body portion 9a and extended portions 9b and 9c provided on both sides in the width direction W orthogonal to the curved direction C (see FIG. 7) of the main body portion 9a.
　本体部分９ａは、湾曲した矩形形状の表皮開口部６ａに対応する矩形形状の開口９ｄを有する。補強プレート９を曲面部分６ｂに沿って湾曲させた状態では、開口９ｄは、前記曲線方向Ｃに湾曲した表皮開口部６ａに一致する（図７～９参照）。 The main body portion 9a has a rectangular opening 9d corresponding to a curved rectangular skin opening 6a. When the reinforcing plate 9 is curved along the curved surface portion 6b, the opening 9d coincides with the skin opening 6a curved in the curved direction C (see FIGS. 7 to 9).
　補強プレート９の本体部分９ａは、ベゼル７に重なってベゼル７と協働して表皮６を挟むことができるようにベゼル７の表側当接部７ａに対応する略矩形形状の形状を有する。本体部分９ａは、図６～８に示されるように、表皮６に縫着などによって固着される。具体的には、本体部分９ａは、図６に示されるように、複数の縫着部Ｓにおいて表皮６に縫着されている。 The main body portion 9a of the reinforcing plate 9 has a substantially rectangular shape corresponding to the front side contact portion 7a of the bezel 7 so that the skin 6 can be sandwiched in cooperation with the bezel 7 so as to overlap the bezel 7. As shown in FIGS. 6 to 8, the main body portion 9a is fixed to the skin 6 by sewing or the like. Specifically, as shown in FIG. 6, the main body portion 9a is sewn to the skin 6 at a plurality of sewing portions S.
　延設部分９ｂ、９ｃは、本体部分９ａの幅方向Ｗの両側の側縁につながりベゼル７に重ならない範囲に延設されている。なお、補強プレート９の延設部分９ｂ、９ｃは、本体部分９ａの幅方向Ｗの両側のうちの少なくとも一方の側縁に設けていればよく、パッド５の成形性が悪い箇所のみ延設部分を設けてもよい。 The extended portions 9b and 9c are connected to the side edges on both sides of the main body portion 9a in the width direction W and are extended so as not to overlap the bezel 7. The extension portions 9b and 9c of the reinforcing plate 9 may be provided on at least one side edge of both sides of the main body portion 9a in the width direction W, and the extension portion is provided only at a portion where the moldability of the pad 5 is poor. May be provided.
　それぞれの延設部分９ｂ、９ｃには、スリット９ｅ、９ｆが形成されている。これにより、延設部分９ｂ、９ｃは、図２に示されるように、スリット９ｅ、９ｆよりも幅方向Ｗの外側の部分９ｂ１、９ｃ１と、当該部分９ｂ１、９ｃ１を本体部分９ａにつなぐ接続部分９ｂ２、９ｃ２とを備えた構成になる。 Slits 9e and 9f are formed in the extended portions 9b and 9c, respectively. As a result, as shown in FIG. 2, the extended portions 9b and 9c are connected to the portions 9b1 and 9c1 outside the slits 9e and 9f in the width direction W and the portions 9b1 and 9c1 to the main body portion 9a. The configuration includes 9b2 and 9c2.
　スリット９ｅ、９ｆは、延設部分９ｂ、９ｃにおける幅方向Ｗ外側の部分９ｂ１、９ｃ１が本体部分９ａから独立して弾性変形できるように、曲線方向Ｃに延びている。すなわち、スリット９ｅ、９ｆは、表皮開口部６ａに対応して曲線方向Ｃに湾曲した開口９ｄの幅方向Ｗの両側の側縁と平行な方向（すなわち曲線方向Ｃ）に延びている。 The slits 9e and 9f extend in the curved direction C so that the outer portions 9b1 and 9c1 in the width direction W in the extended portions 9b and 9c can be elastically deformed independently of the main body portion 9a. That is, the slits 9e and 9f extend in a direction parallel to the side edges on both sides of the width direction W of the opening 9d curved in the curved direction C corresponding to the epidermis opening 6a (that is, the curved direction C).
　スリット９ｅ、９ｆは、補強プレート９のうちベゼル７に挟まれるベゼル７直下の本体部分９ａとベゼル７両側にはみ出ている延設部分９ｂ、９ｃの幅方向Ｗの外側の部分９ｂ１、９ｃ１とを分離する。これによって、本体部分９ａの両側にはみ出ている延設部分９ｂ、９ｃの幅方向Ｗの外側の部分９ｂ１、９ｃ１を、部分的に曲げやすくして表皮６の曲面部分６ｂを内方から支持する板バネとして機能させることができる。 The slits 9e and 9f form a main body portion 9a directly below the bezel 7 sandwiched between the bezels 7 and extending portions 9b and 9c extending on both sides of the bezel 7 and 9b1 and 9c1 outside the width direction W of the reinforcing plate 9. To separate. As a result, the extending portions 9b and 9c protruding from both sides of the main body portion 9a and the outer portions 9b1 and 9c1 in the width direction W are partially bent easily to support the curved surface portion 6b of the skin 6 from the inside. It can function as a leaf spring.
　延設部分９ｂ、９ｃの曲げ剛性は、表皮６の外側から外力が加わっても反力によって表皮６の曲面部分６ｂが元の湾曲形状に戻ることが可能な弾力性を生む程度の曲げ剛性であればよい。 The flexural rigidity of the extended portions 9b and 9c is such that the curved surface portion 6b of the epidermis 6 can return to the original curved shape due to the reaction force even if an external force is applied from the outside of the epidermis 6. All you need is.
　補強プレート９の一対のスリット９ｅ、９ｆのうち、補強プレート９における上記の側縁６ｄと表皮開口部６ａとの間に挟まれた範囲に位置するスリット９ｅ（図２～４、図６における左側のスリット）は、当該スリット９ｅの長手方向の両端９ｅ１、９ｅ２が閉じるように形成されている。このような両端９ｅ１、９ｅ２が閉じられたスリット９ｅが形成されることによって、延設部分９ｂの幅方向Ｗ外側の部分９ｂ１の両端は、本体部分９ａに対して一対の接続部分９ｂ２を介して部分的につながっているが、両端以外の部分ではつながっていない、いわゆる両端支持の状態になる。これにより、延設部分９ｂは、表皮６の外側からの力を受けたときに大きな反力を発生して表皮６の曲面部分６ｂに沿わせることが可能になる。 Of the pair of slits 9e and 9f of the reinforcing plate 9, the slits 9e located in the range sandwiched between the side edge 6d of the reinforcing plate 9 and the skin opening 6a (left side in FIGS. 2 to 4 and 6). The slit) is formed so that both ends 9e1 and 9e2 of the slit 9e in the longitudinal direction are closed. By forming such a slit 9e in which both ends 9e1 and 9e2 are closed, both ends of the portion 9b1 outside the width direction W of the extending portion 9b are connected to the main body portion 9a via a pair of connecting portions 9b2. It is in a so-called both-end support state, in which it is partially connected but not connected at any part other than both ends. As a result, the extended portion 9b can generate a large reaction force when receiving a force from the outside of the skin 6, and can be aligned with the curved surface portion 6b of the skin 6.
　一方、延設部分９ｃは、片方が開放されたスリット９ｆ（図２～４、図６における右側のスリット）が形成されることによって、幅方向Ｗ外側の部分９ｃ１が接続部分９ｃ２を介して片持ち支持の状態になっており、パッド５（図９参照）に沿いやすいように曲げ剛性が調整されている。図９に示されるパッド開口部５ａの右側部分は、パッド５の成形性が良いため、補強プレート９の反力を利用しての表皮６の曲面部分６ｂの形状保持をする必要はなく、パッド５を表皮６側に押し当てることによりきれいな外観形状を出すことが可能である。 On the other hand, in the extended portion 9c, a slit 9f (the slit on the right side in FIGS. 2 to 4 and 6) is formed so that the portion 9c1 outside the width direction W is separated through the connecting portion 9c2. It is in a holding and supporting state, and its bending rigidity is adjusted so that it can easily follow the pad 5 (see FIG. 9). Since the right side portion of the pad opening 5a shown in FIG. 9 has good moldability of the pad 5, it is not necessary to use the reaction force of the reinforcing plate 9 to maintain the shape of the curved surface portion 6b of the skin 6, and the pad By pressing 5 against the skin 6 side, it is possible to obtain a beautiful appearance shape.
　補強プレート９の一対のスリット９ｅ、９ｆは、補強プレート９における本体部分９ａに重なっているベゼル７の周縁に隣接する位置に形成されている。 The pair of slits 9e and 9f of the reinforcing plate 9 are formed at positions adjacent to the peripheral edge of the bezel 7 overlapping the main body portion 9a of the reinforcing plate 9.
　また、図９に示されるように、表皮６の表皮開口部６ａを構成する当該開口部６ａの周縁部分を、補強プレート９の開口９ｄの内側に巻き込むようにしてもよい。 Further, as shown in FIG. 9, the peripheral edge portion of the opening 6a constituting the skin opening 6a of the skin 6 may be wound inside the opening 9d of the reinforcing plate 9.

　（１）本実施形態のシート１では、表皮６の曲面部分６ｂにおいて当該曲面部分６ｂに沿うように所定の曲線方向Ｃに湾曲した表皮開口部６ａが形成されている。弾性変形可能な板状の補強プレート９は、ベゼル７に重なってベゼル７と協働して表皮６を挟む本体部分９ａと、本体部分９ａの前記曲線方向Ｃに直交する幅方向Ｗの側縁につながりベゼル７に重ならない範囲に延設された延設部分９ｂ、９ｃとを有している。延設部分９ｂ、９ｃには、スリット９ｅ、９ｆが形成されている。スリット９ｅ、９ｆは、延設部分９ｂ、９ｃにおける幅方向Ｗ外側の部分９ｂ１、９ｃ１が本体部分９ａから独立して弾性変形できるように、曲線方向Ｃに延びている。 (Characteristics of this embodiment)
(1) In the sheet 1 of the present embodiment, an epidermis opening 6a curved in a predetermined curved direction C is formed in the curved surface portion 6b of the epidermis 6 along the curved surface portion 6b. The elastically deformable plate-shaped reinforcing plate 9 has a main body portion 9a that overlaps the bezel 7 and cooperates with the bezel 7 to sandwich the skin 6, and a side edge of the main body portion 9a in the width direction W orthogonal to the curved direction C. It has extended portions 9b and 9c that are connected to the bezel 7 and are extended so as not to overlap the bezel 7. Slits 9e and 9f are formed in the extended portions 9b and 9c. The slits 9e and 9f extend in the curved direction C so that the portions 9b1 and 9c1 outside the width direction W in the extending portions 9b and 9c can be elastically deformed independently of the main body portion 9a.
　したがって、補強プレート９の延設部分９ｂ、９ｃは、これらのスリット９ｅ、９ｆによって本体部分９ａから独立して弾性変形可能になっている。その結果、補強プレート９の延設部分９ｂ、９ｃは、表皮６の曲面部分６ｂに沿いやすくなり、表皮６の曲面部分６ｂに沿いながら当該曲面部分６ｂを外側に押すことにより、当該曲面部分６ｂにおけるしわの発生を抑制することが可能になっている。 Therefore, the extending portions 9b and 9c of the reinforcing plate 9 can be elastically deformed independently of the main body portion 9a by these slits 9e and 9f. As a result, the extended portions 9b and 9c of the reinforcing plate 9 easily follow the curved surface portion 6b of the skin 6, and by pushing the curved surface portion 6b outward while following the curved surface portion 6b of the skin 6, the curved surface portion 6b It is possible to suppress the occurrence of wrinkles in.
　言い換えれば、補強プレート９にスリット９ｅ、９ｆが形成されていない場合には、補強プレート９の剛性が高いので、補強プレート９が表皮６に沿いにくく、ベゼル７の形状に沿って湾曲する。そのため、補強プレート９が表皮６に沿わず、ベゼル７の周辺の表皮６の外観にしわが発生するなどの影響が出る。一方、本実施形態のように補強プレート９にスリット９ｅ、９ｆが形成されることにより、スリット９ｅ、９ｆよりも外側の延設部分９ｂ、９ｃの剛性を部分的に下げて当該延設部分９ｂ、９ｃを表皮６に沿いやすくしている。このように、スリット９ｅ、９ｆが形成されることにより、延設部分９ｂ、９ｃに反力が発生し、スリット９ｅ、９ｆから外側の延設部分９ｂ、９ｃを表皮６に沿わせることが可能になる。また、表皮６の曲面部分６ｂに外力が加わって変形しても、補強プレート９の延設部分９ｂ、９ｃの反力によって当該曲面部分６ｂは元の形状に戻ることが可能になる。 In other words, when the slits 9e and 9f are not formed in the reinforcing plate 9, the rigidity of the reinforcing plate 9 is high, so that the reinforcing plate 9 is difficult to follow the skin 6 and curves along the shape of the bezel 7. Therefore, the reinforcing plate 9 does not follow the skin 6, and the appearance of the skin 6 around the bezel 7 is wrinkled. On the other hand, by forming the slits 9e and 9f in the reinforcing plate 9 as in the present embodiment, the rigidity of the extension portions 9b and 9c outside the slits 9e and 9f is partially lowered to partially reduce the rigidity of the extension portions 9b. , 9c is made easier to follow the epidermis 6. By forming the slits 9e and 9f in this way, a reaction force is generated in the extending portions 9b and 9c, and the extending portions 9b and 9c outside the slits 9e and 9f can be aligned with the skin 6. become. Further, even if the curved surface portion 6b of the skin 6 is deformed by applying an external force, the curved surface portion 6b can return to the original shape due to the reaction force of the extending portions 9b and 9c of the reinforcing plate 9.
　（２）本実施形態のシート１では、補強プレート９は、熱可塑性樹脂板で構成されているので、表皮６の曲面部分６ｂに沿うように曲がりやすく、しかも当該曲面部分６ｂを外側に押すことが可能な曲げ剛性を有する。すなわち、熱可塑性樹脂板で構成された補強プレート９は、曲げやすくしかも剛性があり、適度に曲がるため、表皮６の曲面部分６ｂに沿いやすいという利点を有する。 (2) In the sheet 1 of the present embodiment, since the reinforcing plate 9 is made of a thermoplastic resin plate, it is easy to bend along the curved surface portion 6b of the skin 6, and the curved surface portion 6b is pushed outward. Has a bending rigidity that allows. That is, the reinforcing plate 9 made of a thermoplastic resin plate has an advantage that it is easy to bend, has rigidity, and bends appropriately, so that it easily follows the curved surface portion 6b of the skin 6.
　なお、本発明の補強部材は、上記の熱可塑性樹脂板で構成された補強プレート９以外であっても、弾性変形可能で表皮６の曲面部分６ｂに沿わせることが可能なものであればよい。 The reinforcing member of the present invention may be other than the reinforcing plate 9 made of the above-mentioned thermoplastic resin plate as long as it can be elastically deformed and can be aligned with the curved surface portion 6b of the skin 6. ..
　（３）本実施形態のシート１では、表皮開口部６ａは、シート１の側縁（具体的には、図１および図９に示されるシート１の幅方向Ｘにおける表皮６の側縁６ｄ）に近い位置に形成されている。スリット９ｅは、補強プレート９におけるシート１の側縁（すなわち、表皮６の側縁６ｄ）と表皮開口部６ａとの間に挟まれた範囲において、当該スリット９ｅの長手方向の両端が閉じるように形成されている。 (3) In the sheet 1 of the present embodiment, the skin opening 6a is the side edge of the sheet 1 (specifically, the side edge 6d of the skin 6 in the width direction X of the sheet 1 shown in FIGS. 1 and 9). It is formed at a position close to. The slit 9e is formed so that both ends in the longitudinal direction of the slit 9e are closed in the range sandwiched between the side edge of the sheet 1 (that is, the side edge 6d of the skin 6) and the skin opening 6a in the reinforcing plate 9. It is formed.
　上記のように表皮６の表皮開口部６ａがシートの側縁に近い位置に形成されている場合には、当該表皮開口部６ａとシートの側縁との間に挟まれた狭い範囲では、当該表皮６に覆われる被覆対象（パッドなど）の成形性が悪いなどの理由により、表皮６にしわが発生しやすい傾向がある。そこで、上記のように、補強プレート９におけるシートの側縁と表皮開口部６ａとの間に挟まれた範囲において、当該スリット９ｅの長手方向の両端が閉じるように形成されていることにより、補強プレート９の延設部分９ｂは、スリット９ｅの両端付近の２つの箇所において本体部分９ａに支持（すなわち両端支持）される。これにより、延設部分９ｂの曲げ剛性が向上し、表皮６における表皮開口部６ａとシートの側縁との間に挟まれた範囲におけるしわの発生を確実に抑制させることが可能である。 When the skin opening 6a of the skin 6 is formed at a position close to the side edge of the seat as described above, in the narrow range sandwiched between the skin opening 6a and the side edge of the seat, the said The skin 6 tends to be wrinkled due to poor moldability of the covering object (pad or the like) covered with the skin 6. Therefore, as described above, the slit 9e is reinforced by being formed so that both ends in the longitudinal direction of the slit 9e are closed in the range sandwiched between the side edge of the sheet and the skin opening 6a of the reinforcing plate 9. The extended portion 9b of the plate 9 is supported by the main body portion 9a (that is, supported at both ends) at two locations near both ends of the slit 9e. As a result, the bending rigidity of the extended portion 9b is improved, and it is possible to reliably suppress the occurrence of wrinkles in the range sandwiched between the skin opening 6a and the side edge of the seat in the skin 6.
　また、表皮６における表皮開口部６ａとシートの側縁との間に挟まれた範囲において、ベゼル７からの押圧による表皮６の沈み込みを低減することも可能である。 Further, it is also possible to reduce the sinking of the skin 6 due to the pressing from the bezel 7 in the range sandwiched between the skin opening 6a of the skin 6 and the side edge of the seat.
　言い換えれば、ベゼル７の両側のうち、図２および図９に示されるベゼル７の左側（すなわち、シートの側縁付近であって、パッド５の成形性が悪くて表皮６にしわが発生しやすい部分）では、スリット９ｅは、両端が閉じたスリットの形態にして、ベゼル７の左側にはみ出ている延設部分９ｂの曲げ剛性（ばね性）を上げている。 In other words, of both sides of the bezel 7, the left side of the bezel 7 shown in FIGS. 2 and 9 (that is, the portion near the side edge of the seat where the pad 5 has poor moldability and the skin 6 is prone to wrinkles. ), The slit 9e is in the form of a slit with both ends closed to increase the flexural rigidity (springiness) of the extended portion 9b protruding to the left side of the bezel 7.
　とくに、表皮開口部６ａがシートの側縁に近い位置に設けられている場合には、表皮開口部６ａとシートの側縁に挟まれた狭い領域では表皮６にしわが発生しやすいとともに下方へ沈み込んだように見えやすい部分であるが、両端が閉じたスリット９ｅによって、表皮６におけるしわの軽減と沈み込みの防止を両方達成することが可能である。 In particular, when the skin opening 6a is provided near the side edge of the seat, the skin 6 is likely to wrinkle and sink downward in a narrow area sandwiched between the skin opening 6a and the side edge of the seat. Although it is a part that looks like it is crowded, the slit 9e with both ends closed makes it possible to achieve both reduction of wrinkles and prevention of sinking in the epidermis 6.
　図６に示されるように、両端が閉じているスリット９ｅの長さＬは、５０ｍｍ程度の長さ（例えば、４０～６０ｍｍ程度）が好ましい。このような長さのスリット９ｅを形成することにより、延設部分９ｂは、表皮６の曲面部分６ｂへ沿うように確実に変形し、かつ、表皮６の曲面部分６ｂを外側へ押し出してしわの発生を確実に防止しうる曲げ剛性を得ることが可能になる。 As shown in FIG. 6, the length L of the slit 9e with both ends closed is preferably about 50 mm (for example, about 40 to 60 mm). By forming the slit 9e having such a length, the extended portion 9b is surely deformed along the curved surface portion 6b of the skin 6, and the curved surface portion 6b of the skin 6 is pushed outward to cause wrinkles. It is possible to obtain bending rigidity that can surely prevent the occurrence.
　また、延設部分９ｂの幅方向外側の部分９ｂ１の幅Ｐは、１８ｍｍ程度（例えば、１４～２２ｍｍ程度）であれば、上記のベゼル７近傍の範囲で表皮６のしわの発生を確実に防止することが可能であり、表皮６の外観向上に寄与する。また、シート１の側縁に近い延設部分９ｂについては、幅Ｐを１８ｍｍ程度にすれば、表皮６の内側を構成するインナーカバーなどに接触しないので好ましい。 Further, if the width P of the portion 9b1 outside the width direction of the extension portion 9b is about 18 mm (for example, about 14 to 22 mm), wrinkles of the skin 6 are surely prevented in the range near the bezel 7. It is possible to improve the appearance of the epidermis 6. Further, it is preferable that the width P of the extended portion 9b near the side edge of the sheet 1 is about 18 mm because it does not come into contact with the inner cover or the like constituting the inside of the skin 6.
　（４）本実施形態のシート１では、スリット９ｅ、９ｆは、補強プレート９における本体部分９ａに重なっているベゼル７の周縁に隣接する位置に形成されている。この構成では、ベゼル７の周縁に隣接する位置にスリット９ｅ、９ｆが形成されているので、ベゼル７の周縁と表皮６の曲面部分６ｂにおける延設部分９ｂ、９ｃで外側に押されている部分との間隔を小さくすることが可能である。これにより、補強プレート９が表皮６に沿わない部分を無くして表皮６の外観を向上することが可能である。 (4) In the sheet 1 of the present embodiment, the slits 9e and 9f are formed at positions adjacent to the peripheral edge of the bezel 7 overlapping the main body portion 9a of the reinforcing plate 9. In this configuration, since the slits 9e and 9f are formed at positions adjacent to the peripheral edge of the bezel 7, the peripheral portion of the bezel 7 and the portion pushed outward by the extended portions 9b and 9c in the curved surface portion 6b of the skin 6. It is possible to reduce the distance between and. As a result, it is possible to improve the appearance of the skin 6 by eliminating the portion where the reinforcing plate 9 does not follow the skin 6.
　（５）本実施形態のシート１では、補強プレート９の延設部分９ｂ、９ｃは、本体部分９ａの幅方向Ｗの両側の側縁から延設され、それぞれの延設部分９ｂ、９ｃと本体部分９ａとの間に形成されたスリット９ｅ、９ｆによって本体部分９ａから独立して弾性変形可能になっている。したがって、補強プレート９の幅方向Ｗの両側の延設部分９ｂ、９ｃによって、表皮６の曲面部分６ｂにおけるしわの発生を抑制することが可能になる。 (5) In the sheet 1 of the present embodiment, the extending portions 9b and 9c of the reinforcing plate 9 are extended from the side edges on both sides of the main body portion 9a in the width direction W, and the extending portions 9b and 9c and the main body are respectively extended. The slits 9e and 9f formed between the portion 9a and the portion 9a make it elastically deformable independently of the main body portion 9a. Therefore, the extension portions 9b and 9c on both sides of the reinforcing plate 9 in the width direction W can suppress the occurrence of wrinkles on the curved surface portion 6b of the skin 6.
　（６）本実施形態のシート１では、補強プレート９の本体部分９ａは、表皮６の外側のベゼル７と重なっている。本体部分９ａが表皮６に縫着されることにより、縫着部分がベゼル７によって覆われて外部から見えなくなる。その結果、表皮６の見栄えの低下を防ぐことが可能である。 (6) In the sheet 1 of the present embodiment, the main body portion 9a of the reinforcing plate 9 overlaps with the bezel 7 on the outside of the skin 6. When the main body portion 9a is sewn to the skin 6, the sewn portion is covered with the bezel 7 and becomes invisible from the outside. As a result, it is possible to prevent the appearance of the epidermis 6 from being deteriorated.
　（７）本実施形態のシート１では、表皮開口部６ａは、チャイルドシートのコネクタを挿入可能な大きさを有しており、それによってシート１へのチャイルドシートの取付けを許容する。これにより、シート１におけるチャイルドシートのコネクタ挿入用の開口（すなわち表皮開口部６ａ）周辺における表皮６のしわの発生を抑制することが可能になる。 (7) In the seat 1 of the present embodiment, the skin opening 6a has a size in which the connector of the child seat can be inserted, thereby allowing the child seat to be attached to the seat 1. This makes it possible to suppress the occurrence of wrinkles in the skin 6 around the opening (that is, the skin opening 6a) for inserting the connector of the child seat in the seat 1.
　（８）また、本実施形態では、補強プレート９のスリット９ｅよりも外側の延設部分９ｂの下方に延びている部分９ｂ３（図２および図６参照）は、表皮６（例えば図１に示される表皮６の吊り込み部分６ｃなど）に縫着されていてもよい。これにより、補強プレート９の剛性を利用して表皮６の外観の折れしわを抑制することが可能になる。 (8) Further, in the present embodiment, the portion 9b3 (see FIGS. 2 and 6) extending below the extending portion 9b outside the slit 9e of the reinforcing plate 9 is shown in the skin 6 (for example, FIG. 1). It may be sewn on the hanging portion 6c of the skin 6). This makes it possible to suppress wrinkles on the appearance of the skin 6 by utilizing the rigidity of the reinforcing plate 9.

It has an extension portion that is connected to the edge and extends so as not to overlap the pressing member, and a slit is formed in the extension portion. The slit extends in the curved direction so that the outer portion in the width direction of the extended portion can be elastically deformed independently of the main body portion.
